Pattaya's best weather by a wide margin: dry, sunny days and the lowest humidity of the year, with cool evenings from December into mid-February that can call for a light sweatshirt. It's also the busiest and priciest stretch, book Jomtien and Pattaya Beach hotels well ahead if visiting over the December to February window.

This tier spans two different halves of the year. March and April are still technically dry season, but the heat builds toward its yearly peak and pre-monsoon showers start creeping in. June and July sit within the monsoon's calmer middle, rain is frequent but rarely severe, and it's common to get long dry stretches even in the wettest months. November, right as the rainy season winds down, sees rainfall drop off fast, making it one of the more pleasant months despite technically still being inside the rainy season.

The wettest stretch of the year, when September and October bring the heaviest rain totals and the most rain days, along with the year's highest humidity. Showers are usually short, heavy downpours rather than all-day washouts, and it's not unusual for the weather to stay decent for weeks even in August, but this is when hotel prices drop to their lowest of the year.
